{{/*
Container env, merged so every name is emitted exactly once — Helm 4 applies
manifests with server-side apply, which rejects duplicate env names
(helm/helm#31529); Helm 3 silently used the last entry.

Value precedence (which definition wins on a name clash), lowest first:
  env.common < computed console/service URLs < template defaults ("extra") < env.<service>
(computed URLs must beat env.common: the in-cluster CONSOLE_URL already folds
in env.common.CONSOLE_URL as its own fallback via jitsu-dev.consoleUrl.)

Emission order (independent of precedence) is chart-provided bases first, user
config last — by the phase that produced each name's *winning* value, ordered:
computed, extra, env.common, env.<service>. Kubernetes $(VAR) expansion only
sees vars defined earlier in the list, so a name whose value references another
must render after it: a user override like env.common.A="$(HTTP_PORT)" emits
after the chart's HTTP_PORT, and even env.<service>.CONSOLE_URL="$(HTTP_PORT)"
(overriding a computed key) emits at the service phase, after HTTP_PORT.
Limitation: two overrides in the *same* phase referencing each other still
order alphabetically — expansion between them is not guaranteed.

Args (dict):
  ctx      — root template context (required)
  service  — key into .Values.env for per-service overrides (required)
  extra    — dict of service-specific defaults the template used to hardcode
  exclude  — list of names the template emits manually (valueFrom entries),
             so a per-service override can't duplicate them
